The reactions of 2,4,6-trinitroethylbenzene (TNEB) with diethylamine (DEA) in N,N-dimethylformamide (DMF) solvent and 1,1',3,3'-tetramethylguanidine (TMG) in dimethyl sulfoxide (DMSO) solvents have been studied with respect to products and kinetics.The proton transfer reaction was observed with insignificant ?-complex formation.The equilibrium constants are large, K=2717 and 497 dm3mol-1 for the reaction of TMG and DEA, respectively.The rate constants are small, kH25=1.3*10-2 and 1.5*10-2 dm3mol-1s-1 for the reaction with TMG and DEA, respectively, and these reactions show large primary deuterium kinetic isotope effects kH/kD=9.1 and 10.The rate constants, activation parameters and primary deuterium kinetic isotope effects are compared to those for proton transfer from trinitrocumene TNC, and trinitroethylbenzene TNEB to tetyramethylguanidine in DMF solvent.
